A field guide to public pianos.

Somewhere near you, there is probably a piano sitting in a train station, a park, or a market square, waiting for anyone who walks by to sit down and play. Keys is a map of those pianos. Where they are, what they're like, and whether they're still there.

We started with 11,057 pianos pulled from OpenStreetMap, and we're growing the map with the people who actually play them. Photos, notes, and check-ins that tell you what a listing never could.

Found one that isn't here, or one that's gone? Add it or flag it. Every edit makes the guide better for the next person carrying sheet music and looking for somewhere to play.
